Question 1: Identify three common hazards that might occur during the manufacturing of a plastic product. Explain how each hazard could pose a risk to the user or the manufacturer.

Answer: Possible hazards include: 1) Sharp edges during cutting, which could cause cuts; 2) Hot surfaces from manufacturing equipment, risking burns; 3) Toxic fumes from certain plastics or chemicals, which could be harmful if inhaled. Each hazard poses risks of injury or health issues if not properly controlled.

Question 2: Describe two safety features or protective measures that should be included in a workshop where students are making metal components. Explain their importance.

Answer: Safety features include: 1) Safety goggles to protect eyes from metal shards and sparks; 2) Protective gloves to prevent cuts and burns. These measures help prevent injuries and ensure safe handling of tools and materials.

Question 3: Sketch a safety guard for a circular saw used in a workshop. The guard should cover the blade when not in use but allow safe operation. Label the key parts of your design.

Answer: A correct sketch would show a semi-circular or protective cover that encloses the blade, with a hinge or sliding mechanism for access. Labels should include: blade cover, hinge or sliding mechanism, safety latch, and attachment points.

Question 4: Explain why it is important to wear personal protective equipment (PPE) when making products that involve cutting, shaping, or finishing materials.

Answer: Wearing PPE such as goggles, gloves, and masks protects against flying debris, chemical exposure, and inhalation of dust or fumes, reducing the risk of injury or health problems.

Question 5: Identify a common safety mistake that could occur during the assembly of a product and suggest a way to prevent it.

Answer: A common mistake is not securing parts properly before drilling, which can cause parts to spin or slip. To prevent this, always clamp parts securely before working on them.

Question 6: Draw a simple safety signage symbol that could be used in a workshop to warn about the risk of hot surfaces. Include a brief description of what the symbol should depict.

Answer: A correct sketch would show a hand with heat waves rising from a surface, indicating hot surfaces. The symbol should be clear, simple, and recognizable as a warning about heat.

Question 7: List three safety procedures that should be followed when using power tools in a classroom setting.

Answer: Procedures include: 1) Always read and follow the manufacturer's safety instructions; 2) Keep hair and loose clothing away from moving parts; 3) Ensure the tool is turned off and unplugged when not in use or when changing accessories.

Question 8: Explain how the design of a product can incorporate safety features to prevent accidental injury during everyday use.

Answer: Design features such as rounded edges, safety locks, non-slip surfaces, and protective covers help prevent cuts, slips, and accidental activation, making the product safer for users.

Question 9: Plan and sketch a safety lock mechanism for a storage cabinet intended for school use. The lock should prevent access by children but be easy for adults to operate. Label the main parts of your design.

Answer: A correct plan would include a simple locking mechanism such as a latch combined with a key or combination lock. Labels should include: lock body, latch, key or combination interface, and mounting points.
